Difficulty: HardPharmacological and Parenteral Therapies

A 14-day-old neonate is admitted to the neonatal intensive care unit with suspected bacterial meningitis. The neonate has a single peripheral intravenous (IV) catheter infusing Lactated Ringer's solution at 10 mL/hr10 \text{ mL/hr}. The healthcare provider prescribes a stat dose of intravenous ceftriaxone 50 mg/kg50 \text{ mg/kg}. Which of the following is the priority nursing action?

  1. Withhold the medication and contact the healthcare provider to request an alternative antibiotic prescription.Answer
  2. B
    Pause the continuous infusion, thoroughly flush the IV line with normal saline, administer the medication, and flush again.
  3. C
    Establish a second peripheral IV access site to administer the medication independently of the primary infusion.
  4. D
    Connect the medication to the lowest Y-site port on the primary tubing to minimize the contact time between the two solutions.

Answer

The priority action is to withhold the ceftriaxone and contact the healthcare provider for a different antibiotic.
Ceftriaxone is contraindicated in neonates (28 days of age or younger) if they are receiving any calcium-containing intravenous fluids, such as Lactated Ringer's or total parenteral nutrition (TPN). This is due to the high risk of fatal ceftriaxone-calcium precipitates forming in the neonate's lungs and kidneys. Unlike in older pediatric and adult populations, these solutions cannot be given sequentially or even through separate IV lines in neonates. The nurse must recognize this critical safety alert, withhold the medication, and contact the provider for an alternative antibiotic (such as cefotaxime).

Step-by-Step Solution

1
Analyze the prescribed medication and the current continuous infusion.
The medication is ceftriaxone, and the continuous infusion is Lactated Ringer's, which contains calcium.
Identifying components of IV fluids is essential for determining drug-drug compatibilities.
2
Evaluate the patient's demographic information against medication safety alerts.
The patient is a 14-day-old neonate.
Age is a critical factor in pharmacokinetics and drug safety, particularly for neonates (28 days or younger).
3
Determine the specific contraindication related to this clinical scenario.
Ceftriaxone and calcium-containing solutions are strictly contraindicated in neonates due to the risk of fatal ceftriaxone-calcium precipitates in the lungs and kidneys.
Unlike older clients, neonates cannot receive these two solutions even through separate lines or sequentially.
4
Select the safest nursing intervention.
The nurse must withhold the dose and clarify the prescription with the provider to obtain a safe alternative.
Patient safety is the highest priority; administering the drug would cause severe harm.
